Inflammation and Psoriasis: A Comprehensive Review.

Psoriasis is an immune-mediated disease with a strong genetic component that brings many challenges to sick individuals, such as chronic illness, and which has multiple associated comorbidities like cardiovascular disease, metabolic syndrome, inflammatory bowel disease, and psychological disorders. Understanding the interplay between the innate and adaptative immune system has led to the discovery of specific cytokine circuits (Tumor Necrosis Factor-alpha (TNF-α), IL-23, IL-17), which has allowed scientists to discover new biomarkers that can be used as predictors of treatment response and pave the way for personalized treatments. In this review, we describe the footprint psoriasis leaves on the skin and beyond, key pathophysiological mechanisms, current available therapeutic options, and drawbacks faced by existing therapies, and we anticipate potential future perspectives that may improve the quality of life of affected individuals.

Immunohistochemical study of psoriatic plaques and perilesional skin in psoriasis vulgaris patients: A pilot study.

Psoriasis vulgaris, a chronic inflammatory skin disorder, is the result of immune mediated processes, genetic background and environmental factors. Prolactin and the vascular endothelial growth factor seem to play a key role in psoriasis pathogenesis regarding hyperproliferation of epidermal keratinocytes and dermal vascular ectasia. The aim of the study was to investigate the expression of tumor necrosis factor-α (TNF-α), vascular endothelial growth factor receptor 2 (VEGFR2) and prolactin receptor (PRLR) in psoriatic skin by immunohistochemical analysis and to evaluate the correlation with disease severity.

Relationship between etanercept and thyroid function in patients with psoriasis vulgaris.

Background And Aim: Psoriasis vulgaris, a chronic inflammatory skin disease, requires a long term medication, in order to avoid relapsing episodes. TNF-alpha, one of the targeted molecule in psoriasis therapy, seems to be also involved in thyroid disorders etiopathogenesis. The aim of this study was to evaluate the relationship between anti TNF-alpha therapy and thyroid parameters: serum level of triiodothyronine (T3), free thyroxine (FT4), thyroid-stimulating hormone (TSH) and antithyroidperoxidase antibody (AbTPO) in psoriasis treated population.

Hair loss and regeneration performed on animal models.

Research in the field of reversal hair loss remains a challenging subject. As Minoxidil 2% or 5% and Finasteride are so far the only FDA approved topical treatments for inducing hair regrowth, research is necessary in order to improve therapeutical approach in alopecia. In vitro studies have focused on cultures of a cell type - dermal papilla or organ culture of isolated cell follicles.

Topical Products for Human Hair Regeneration: A Comparative Study on an Animal Model.

Background: Hair loss and hair growth is the subject of tremendous amount of research.

Objective: This study investigated the efficacy of three chemical treatments used in humans for hair loss, using a rat model of hair regrowth. The products tested were 2% minoxidil, Hairgrow (Dar-Al-Dawa Pharma), Aminexil, Dercos (Vichy Laboratoires), and Kerium, Anti-chute (La Roche-Posay).

Antiandrogenic Therapy with Ciproterone Acetate in Female Patients Who Suffer from Both Androgenetic Alopecia and Acne Vulgaris.

Background: Androgenetic Alopecia in Women (AGA) occurs due to an underlying susceptibility of hair follicles to androgenic miniaturization, caused by androgens. Clinically, AGA is characterized by progressive hair loss, with a marked hair thinning in the fronto-parietal area so that the scalp can be easily seen. Acne vulgaris is androgen-dependent and often affects the skin that has an increased number of oil glands: face, back and chest.
